Hi all.
I am newbie from Italy (sorry for my bad English…)
I use Designer on Mac (a PowerBook with Mojave and a iMac with BigSur) and I have the same problem already reported: (I just tried with version 1.9.1 and the problem is always present), with a difference: for my job I often use other programs (i.e. Rhinoceros) which allows me to export 2D drawings in AI format.
These drawings, when opened directly with Designer, turn out completely blank. If, on the other hand, I open them with Illustrator and save them again with Illustrator, without changing anything (or making only small changes), Designer manages to open them and the drawing is perfectly visible.
In my case, then, Designer can only read the AI format if the document was saved with Illustrator.
I'd be happy if someone could let me know how to directly open AI files saved by other programs, without having to go through Illustrator itself.
Thanks for your attention. Regards.
Diego
